Anthurium eminens was first published to science in 1855. Based on information provided by Dutch naturalist Joep Moonen (yupe or jupe), who guides botanists and tourists into the rain forest of French Guiana, northern Brazil, and Suriname, Anthurium eminens is considered a rare species in French Guiana. Both an epiphyte (ep-a-FIT) and a hemiepiphyte (hem-a-EPA-fit), the species grows on the trunks of trees. An epiphyte is a plant that grows upon another plant as a result of a seed being deposited on the tree by a monkey, bird or other rain forest inhabitant in their droppings. A hemiepiphyte is similar but can also climb the tree as a result of a seed that has germinated in the ground. The species is normally found 3 meters (10 feet) or higher up the host tree and is a member of Anthurium section Dactylophyllium, a group with palmately compound leaf blades.
Joep has observed Anthurium eminens in French Guiana on the Approuage River, near the Oiapoque River, and on the French side of the Rio Matabo . He reports Anthurium eminens grows in shade with less than 50% sunlight. He has also observed that the species is rarely seen producing an inflorescence.
An aroid, all Anthurium species reproduce via the production an inflorescence. The stalk that supports the entire inflorescence is the peduncle. When an Anthurium is "in flower" the reference is to the tiny flowers containing both male and female sexual parts that grow on the spadix at the center of the inflorescence. Unlike plants in the genus Philodendron which contain imperfect flowers having only a single sex Anthurium possess perfect flowers containing both sexes. To help prevent self pollination nature has designed the female flowers to be receptive before the male portion of the flower produce their pollen so in most cases an insect must bring pollen from another plant.
The spathe of Anthurium eminens is green with a purple tinge but itself is not a "flower". The spathe is simply a modified leaf. The spadix at its center vaguely resembles an elongated pine cone. The spadix is a spike on a thickened fleshy axis which can produce tiny flowers. Once the female flowers on the spadix have been fertilized by an insect, normally a beetle, they produce berries which in Anthurium emines are purple to purple-red or sometimes a purplish violet. When "in fruit", those berries contain the seeds of the aroid. When the fruit is produced the inflorescence is known to a botanist as an infructesence.
Anthurium eminens has been collected in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Suriname, Venezuela and Peru. Specimens have been observed by field botanists from from 70 meters to over 2100 meters (230 to almost 6700 feet) above sea level. Anthurium eminens is a wide spread species and although rare in French Guiana is often observed in the other portions of its natural range.
In an article on Anthurium eminens written by Anthurium expert Neil Carroll on the International Aroid Society: website http://www.aroid.org/ Neil states the word "eminens" means projecting or eminent. The reference to Anthurium eminens is in result of the aroid's large size. Neil also says the species is scandent. Scandent is a botanical description meaning the species climbs as well as grows close to its host tree.
In the field notes of aroid botanist Dr. Thomas B. Croat Ph.D., P.A. Schulze Curator of Botany at the Missouri Botanical Garden in St. Louis, MO, Dr. Croat states the leaf blades of Anthurium eminens are medium to dark green on the adaxial (upper) leaf surface and are matte to semi-glossy. The leaves are slightly paler in color on the abaxial (underside) of the blade and the blades are subcoriaceous. Subcoriaceous is a description of the thickness of the leaf blade and indicates the blade is just less than leathery to the touch. When a new leaf emerges it is surrounded by a sheath like covering known as a cataphyll. Once the cataphyll dries the base of its fibers remain on the Anthurium. The petioles which support each leaf (often called stems) can be terete to just less than terete (round to less than round) and have also been observed to be shaped like a letter "U" when cut as a cross section.
All aroids including Anthurium eminens variable and do not always appear exactly the same from specimen to specimen. This link explains in non-technical language but greater detail natural variation and morphogenesis (ontogeny). Morphing is commonly seen in Aroid species. Click here.
